Predictive Sampling for Efficient Pairwise Subjective Image Quality Assessment

open access: yesProceedings of the 31st ACM International Conference on Multimedia, 2023
Subjective image quality assessment studies are used in many scenarios, such as the evaluation of compression, super-resolution, and denoising solutions. Among the available subjective test methodologies, pair comparison is attracting popularity due to its simplicity, reliability, and robustness to changes in the test conditions, e.g.

No-Reference Image Quality Assessment and Application Based on Spatial Domain Coding

open access: yesIEEE Access, 2018
Aiming at the problem that a no-reference (NR) image quality assessment algorithm is not accurate enough to predict the image quality at present, we proposed a method of NR image quality assessment based on spatial domain coding (SDC).

Visual Comfort Assessment for Stereoscopic Image Retargeting

open access: yes, 2018
In recent years, visual comfort assessment (VCA) for 3D/stereoscopic content has aroused extensive attention. However, much less work has been done on the perceptual evaluation of stereoscopic image retargeting.

Selecting stimuli parameters for video quality studies based on perceptual similarity distances [PDF]

open access: yes, 2015
This work presents a methodology to optimize the selection of multiple parameter levels of an image acquisition, degradation, or post-processing process applied to stimuli intended to be used in a subjective image or video quality assessment (QA) study ...

No-reference image quality assessment based on quality patches in real time

open access: yesEURASIP Journal on Image and Video Processing, 2018
Image quality assessment methods quantify the quality of an image that is highly correlated with human-perceived image quality. In this paper, the image quality is represented by the image patches that are selected by applying the spatial correlation of ...

Two-way Quality Assessment Approach for Tumour Detection using Free-hand Strain Imaging [PDF]

open access: yes, 2014
A novel two-way image quality assessment method is proposed for free-hand strain imaging. In elasticity imaging, tissue with different stiffness exhibit varying contrast in the strain images and detectability of a lesion is measured using elastographic ...

Subjective and objective quality assessment of transparently encrypted JPEG2000 images [PDF]

open access: yesProceedings of the 12th ACM workshop on Multimedia and security, 2010
Transparent encryption has two main requirements, i.e. security and perceived quality. The perceptual quality aspect has never been thoroughly investigated. In this work, three variants to transparently encrypt JPEG2000 images are compared from a perceptual quality viewpoint.

Perceptual Quality Assessment Based on Visual Attention Analysis [PDF]

open access: yes, 2009
Most existing quality metrics do not take the human attention analysis into account. Attention to particular objects or regions is an important attribute of human vision and perception system in measuring perceived image and video qualities.
